You can pay $100/10% a month on Amazon and get good support. They will debug and guide you on. Hiring someone with the expertise you get would cost magnitudes of order more. And if your enterprise is at the level where it warrants 15k a month support, it is still worth it. Considering that still would barely get you only one skilled person hired.

I've worked in a lot of startups and have never had to pay that whole price until we had decent revenue. The AWS Activate program [1] has been pretty solid for my current company.

There's a big joke going around that AWS is basically a VC that invests in startups with free services and then makes their money back on revenue once they've grown.
